as far as i'm concern you are blacklisted for running out from your loan even you leave it with guarantor.all the loans has an insurance.I prove it because i was in the same situation before.But in your case as what you said that there is a guarantor that you get to cover up your loan.But i think if your guarantor was in trouble right now he will try to locate you more than the bank.Dont enter any GCC country for your safety.
